Title – Capacity Sensitivity: Three Lemmas and Their Application

Abstract – The Shannon capacity for scalar, stationary and memoryless point-to-point channels is a fundamental concept in information theory. However for continuous non-Gaussian channels, there are no closed-form characterizations in most cases. A key question is therefore how to understand the impact of model parameters on the Shannon capacity. In this talk, I will introduce the notion of capacity sensitivity and its analysis. The analysis relies on three lemmas drawn from non-smooth optimization theory in general metric spaces and provides new insights into the impact of variations in the input constraints and the noise distribution. This talk will highlight three aspects: the generality of the methods (beyond additive absolutely continuous noise models); insights into the structure of the optimal input distribution; and on-going work into generalizations of capacity sensitivity for multi-user channels.

(2) From 21-23 March I attended the 52nd Annual Conference on Information Sciences and Systems (CISS) 2018 in Princeton and presented joint work with Samir Perlaza on our most recent results characterizing capacity sensitivity:
